In the battle against the state’s prolonged and brutal drought, Texas Tech University
agricultural researchers have released two new farmer-friendly computer tools that
save scarce irrigation water and boost bottom lines for parched producers.

The internet-based programs are being offered free of charge through the Texas Alliance
for Water Conservation, and take direct aim at improved irrigation scheduling and
resource allocation. Both were developed to specifically target the needs of irrigated
farmers in the West Texas and Panhandle regions.

“They’re designed to help producers make the most out of an irrigation regime, while
remaining conscious of water resources,” said Justin Weinheimer, a research associate
in the Department of Agricultural and Applied Economics.

At the heart of the irrigation scheduling tool is a basic understanding of what scientists
call evapotranspiration or, more simply, the loss of water from the soil both by evaporation
and by transpiration from growing plants.

Specifically, it allows farmers to keep track of soil moisture on a field-by-field
basis for irrigated cotton, corn, sorghum and wheat, using real time weather data
from more than four dozen Texas Tech Mesonet weather stations spread across the plains.
This network of automated stations collects a wide variety of temperature and moisture
levels every 15 minutes.

“The tool allows a producer to customize irrigation scheduling based on field-level
irrigation efficiency, soil moisture readings, and other agronomic and irrigation
characteristics,” Weinheimer said. A checkbook-style water balance then enables the
farmer to determine when and how much water to apply.

The second web-based tool from the Texas Tech team is a resource allocation analyzer.
Put simply, the economic-decision aid is designed for use in the planning season to
determine which crops will maximize the profit potential of a given field.

The resource allocation tool projects crops, yield goals, irrigation requirements
and acreage designations on a field-by-field basis, Weinheimer said. That ability
allows producers to maximize the revenue potential given the irrigation capabilities
of the field.

“It works on the major commodities produced in this region and differs from other
like-tools in that it is farmer friendly, requiring minimal producer input, yet providing
realistic outlooks for producers to consider,” Weinheimer said.

In Texas, virtually no part of the state has been untouched by the drought. City
dwellers along with farmers and ranchers have been besieged by excessive heat and
high winds. Last month, the United States Department of Agriculture designated all
254 counties in Texas natural disaster areas, qualifying them for varying levels of
federal relief.

Even if weather patterns shift and relief-giving rain comes, losses are likely to
head past $3 billion in Texas, state agricultural officials said.
